Senior Software Engineer, Backend (Node.js, TypeScript, Rust)

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real political and financial analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers political report authorship: elections, polling, and political-risk events.

## What you will do

- Author point-in-time political reports and forecasts from a stated evidence cutoff
    
- Make and document directional judgments about polling, win probabilities, and market-implied odds
    
- Explain the causal mechanism behind an event's expected political and market impact
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- Local political analysts with hands-on experience on specific races in swing states: current or upcoming Senate, governor, or statewide contests, or recent cycles in the same state
    
- On-the-ground knowledge of the electorate, the candidates, and the local political environment, from roles such as university political scientist, state or regional pollster, state-level campaign or party analytics staff, or state political-risk analyst
    
- A record of making live judgments about polling, win probabilities, or odds in those races — not retrospective commentary
    
- Strong polling literacy and causal event analysis
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: political science departments and survey research centers at universities in the target states, state and regional pollsters, state-level campaign and party analytics teams, and decision desks or race-ratings outlets with state-specific coverage. National forecasting or political-risk experience is welcome when paired with deep knowledge of a specific state. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Not a fit

- Profiles whose experience is mainly international politics, geopolitics, or country risk, with little or no work on US races
    
- Analysts who have not worked on a current or recent US race in the state they would cover
    
- Pure communications or journalism profiles without demonstrated forecasting, polling, or probabilistic judgment
    
- Academic profiles whose work is purely theoretical, with no analysis of live races
    

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

RN Annotators

## The role

We are hiring native and near-native Hindi speakers to **audit AI training data in their own language**, not to produce it.

You will work across two Amazon Sonic audit collections:

1. **Multilingual Transcription Audit.** You listen to a recording of human or agent speech, read the transcription an annotator produced, and judge whether it accurately captures what the speaker actually said. You apply a fixed set of error codes, assign a pass or fail verdict, and write a short rationale explaining the decision.
    
2. **Forced Alignment Audit.** You review audio that has already been segmented at the word level by an automated system. For each segment you verify that the start and end timestamps match where the word actually begins and ends, and that the reference transcription matches the spoken form. Where the machine got it wrong, you correct the boundary, split a segment, merge two, add a missing one, or remove one that contains no word.
    

Both collections run at 5.00 audit hours per task. Every judgment carries a written reason, so this is careful listening work rather than volume work.

## Who we are looking for

**Native or near-native command of Hindi as spoken in India.** You were either born and raised in a region where this language and variety is dominant, or you are fully fluent with five or more years of residence in such a region. This is a hard requirement.

**Strong English reading and writing.** All conventions, error codes, and audit rationale are written in English, so you need to read a detailed rulebook and write clear feedback in it.

**Disciplined rubric application.** The work rewards people who apply a written standard consistently across hundreds of judgments rather than relying on instinct. Prior transcription, subtitling, localization, linguistic annotation, or QA experience is a strong signal.

**Careful listening.** You can distinguish similar sounds, identify where one word ends and the next begins in continuous speech, and tell genuine acoustic ambiguity apart from a clear annotator error.

Helpful but not required: prior AI data annotation or model evaluation work, a phonetics or linguistics background, and experience with audio editing or waveform tools.

## What the work looks like

You listen, judge, and submit. Where you find an error you tag every applicable error code, not just the first one, and you explain in plain language why the task passed or failed. Critical errors are called out first so the reason for a failure is obvious to the reader.

You will complete a short calibration phase before production work begins.

**Strong English reading and writing.** All conventions, error codes, and audit rationale are written in English, so you need to read a detailed rulebook and write clear feedback in it.

**Disciplined rubric application.** The work rewards people who apply a written standard consistently across hundreds of judgments rather than relying on instinct. Prior transcription, subtitling, localization, linguistic annotation, or QA experience is a strong signal.

**Careful listening.** You can distinguish similar sounds, identify where one word ends and the next begins in continuous speech, and tell genuine acoustic ambiguity apart from a clear annotator error.

Helpful but not required: prior AI data annotation or model evaluation work, a phonetics or linguistics background, and experience with audio editing or waveform tools.

## What the work looks like

You listen, judge, and submit. Where you find an error you tag every applicable error code, not just the first one, and you explain in plain language why the task passed or failed. Critical errors are called out first so the reason for a failure is obvious to the reader.

You will complete a short calibration phase before production work begins.

## The role

We are hiring native and near-native Japanese speakers to **audit AI training data in their own language**, not to produce it.

You will work across two Amazon Sonic audit collections:

1. **Multilingual Transcription Audit.** You listen to a recording of human or agent speech, read the transcription an annotator produced, and judge whether it accurately captures what the speaker actually said. You apply a fixed set of error codes, assign a pass or fail verdict, and write a short rationale explaining the decision.

2. **Forced Alignment Audit.** You review audio that has already been segmented at the word level by an automated system. For each segment you verify that the start and end timestamps match where the word actually begins and ends, and that the reference transcription matches the spoken form. Where the machine got it wrong, you correct the boundary, split a segment, merge two, add a missing one, or remove one that contains no word.

Both collections run at 5.00 audit hours per task. Every judgment carries a written reason, so this is careful listening work rather than volume work.

# **Domain Expert – FP&A (Financial Forecaster)**

**To qualify you must use Financial Forecaster regularly, weekly or more, as a working part of your job, with 5+ years of professional FP&A experience as an FP&A analyst/manager, financial reporting or technical accounting analyst, lender-reporting or treasury analyst, or controller.**

### Financial Forecaster knowledge we require

**Working the model**

- Multidimensional models: navigating models, dimensions and account hierarchies, and reading a cube slice at an exact coordinate rather than at whatever grain the UI lands on
    
- Scenarios: creating one, setting its parent, knowing what it inherits versus holds in its own cells, and locking it — plus identifying the forecast of record by its lock or acceptance date
    
- Accounts and assumptions: telling an input account from a calculated one, and knowing when to fix a figure by editing the account formula versus overriding an assumption cell, because the two are not interchangeable and the grader can tell
    
- CSV imports: loading actuals and driver data, and the unit and scale discipline an import demands
    
- Note surfaces: scenario notes, driver notes, policy notes, planning notes, assumption change logs and variance commentary — and which one a given statement belongs in
    
- Knowing what Financial Forecaster cannot do, so you can recognize a task that asks for a figure or a dimension member the model will never produce
    

**Reading models & packs**

- Reading a scenario fluently: what is an input versus a calculated account, which cells are overridden, what a scenario inherits from its parent versus holds itself
    
- Reading a reporting pack against the model behind it: tracing a printed figure back to the account, scenario and coordinate it came from, and telling a real tie-out from a coincidence
    
- Recognizing the vintage that governs: which scenario is the forecast of record, when it was locked or accepted, and why a later forecast does not silently supersede an approved one
    
- Decoding a coordinate (Time, Entity, Department, Product/Product Line, Region, and facility dimensions like Debtor or Aging Bucket) and knowing what a figure means at that grain versus aggregated
    

**Finding & tying out the number**

- Navigating account hierarchies and scenario trees to locate the figure that actually drives a covenant, a KPI, or a disclosure — targeted retrieval instead of scrolling the model
    
- Unit and scale traps: thousands-versus-dollars mismatches, a cost base that cannot be reconciled to its own revenue, per-period versus LTM versus fiscal-year-to-date, and sniffing out a figure that is off by 10× or 1,000×
    
- Reconciling two in-world sources that disagree, and judging which one governs
    

**Entity structure & governing documents**

- The reporting landscape: legal entity versus department versus segment versus consolidated, and which level a given obligation is measured at
    
- Credit agreement mechanics: the provision fixing the accounting basis (frozen GAAP), Test Periods and test dates, fixed charge coverage and total net leverage, Consolidated EBITDA add-backs and their caps, Consolidated Funded Indebtedness, borrowing base and Eligible Accounts, redetermination, and who must sign a compliance certificate
    
- Case relationships in the financial sense: parent and child scenarios, consolidated versus entity results, and how an amendment, consent or waiver changes the measure going forward
    

**Measure types & classification**

- GAAP versus non-GAAP versus covenant measures, and why the same label can mean three different numbers in one pack
    
- Non-GAAP discipline: exclusions requiring a written determination that an amount is not normal and recurring, reconciliation to the nearest GAAP measure, equal prominence, and restating prior periods when a metric definition changes
    
- Forecast versus projection under the AICPA PFI guidance, range presentations whose endpoints must be comparably likely, and what a reasonably objective basis requires
    
- The standards that decide the answer: going concern and the look-forward window (ASC 205-40), operating segments and the CODM (ASC 280), materiality screening (SAB 99 / Topic 1M), KPI disclosure (Release 33-10751), known trends in MD&A (Reg S-K Item 303), valuation allowances as a discrete item versus through the annual effective rate
    

**Documents, records & workflow**

- Document types: compliance certificate, borrowing base certificate, lender package, board or committee pre-read, earnings release and reconciliation, disclosure committee memo, workpaper, and what each is for
    
- What a finished deliverable requires versus what merely describes it: a correction stated in a memo is not the same as the correction applied in the file or written to the model
    
- App workflow surfaces: scenario creation and locking, saved views, and exports for large result sets
    

## What you'll do

- **Review and QA AI-agent rollouts:** work through completed agent runs in Financial Forecaster and judge whether the agent's answer is correct against the actual model and documents — right scenario, right account, right coordinate, right basis, right conclusion, right deliverable
    
- **Identify failure modes:** pinpoint where and why an agent succeeds too easily or fails wrongly, and flag tasks that are too easy or solvable without actually using Financial Forecaster
    
- **Improve realism and difficulty:** refine the task prompt and the seeded world so tasks reflect authentic FP&A and lender-reporting work and are genuinely hard for a capable agent
    
- **Update grading guidance for accuracy:** sharpen how answers are graded so correct answers pass and wrong ones fail, including gating failures (wrong scenario or vintage used, wrong accounting basis, an add-back taken that the agreement excludes, a figure stated but never written to the model, or a conclusion transcribed from a document that already gave it away)
    
- **Catch plausible-but-wrong answers** that a non-expert reviewer would let slide — a number that looks right at the wrong grain, or a conclusion that is correct in isolation and inconsistent with the rest of the pack
    

## Requirements

- Frequent hands-on Financial Forecaster use for real forecasting, covenant or reporting work in your current or recent role, weekly or more
    
- 5+ years in FP&A, financial reporting, technical accounting, or lender reporting: FP&A analyst/manager, financial reporting analyst, technical accounting analyst, treasury/lender-reporting analyst, or controller
    
- Can read a Financial Forecaster model on sight: tell inputs from calculations, spot an override, identify the governing scenario and its vintage, and judge whether a figure ties at the grain it is stated at
    
- Reflexive with Financial Forecaster's scenario and import mechanics, and with the scale and basis traps that produce confidently wrong numbers
    
- Sound judgment on what a correct, complete answer looks like, and the confidence to mark a plausible answer wrong
    
- **Bonus:** credit agreement compliance and borrowing base reporting; going concern or impairment analysis; segment reporting; SEC reporting or disclosure committee experience; hands-on experience across multiple models and entities, not just one company's single model
    
- **Note:** a CPA, CFA, or MBA is welcome but not required; experienced FP&A analysts and technical accounting specialists are the primary pool

Power Systems Engineer (Substation, Transmission, Interconnection)

## About the Role

Mercor is hiring **residency-trained physicians** across specialties for non-clinical work developing and evaluating clinical AI systems. You will apply your clinical judgment to grading-criteria development, dialogue evaluation, and structured annotation work that determines how these systems are measured.

This is a **non-clinical role** — no direct patient care, and no responsibility for live diagnosis.

**This is a shared expert pool.** After onboarding you may be matched to any of several concurrent clinical workstreams based on your specialty, availability, and interest. You are not committing to a single project, and you may move between streams as priorities shift.

## What you may work on

Work varies by workstream and may include:

- **Grading criteria development** — taking a clinical question and breaking the ideal answer into discrete, checkable criteria, so a model response can be graded consistently rather than impressionistically.
    
- **Clinical dialogue evaluation** — reviewing multi-turn clinical conversations and judging them for accuracy, safety, completeness, appropriate hedging, and whether escalation advice was correct.
    
- **Clinical reasoning annotation** — recording how you would work through a case, including the differential you considered and rejected, not only the conclusion.
    
- **Output review** — flagging hallucinated findings, dangerous omissions, unsupported certainty, and advice that is technically correct but clinically unsafe.
    
- **Guideline authoring** — defining edge cases and standards of care for your specialty so annotation stays consistent across a large group of clinicians.
    
- **Difficult-case writing** — constructing clinical questions that probe the limits of current model reasoning.
    

Task length varies by stream, from roughly 45 minutes for a dialogue evaluation up to an hour or more for grading-criteria authoring. You will get a specific throughput target for whichever stream you are matched to.

## Required qualifications

- **MD or DO** with a **completed residency** in any specialty
    
- **Active, unrestricted medical license** in your country of practice
    
- **3+ years post-residency** clinical experience, practising or previously practising
    
- Comfort writing structured clinical rationale that a non-specialist reviewer can follow
    
- Written and spoken English fluency
    
- **Minimum 20 hours per week**, with the ability to concentrate hours when a stream is time-boxed
    

## Preferred qualifications

- Board certification in your specialty
    
- **U.S. licensure**, and familiarity with U.S. standards of care and clinical guidelines
    
- Primary care, internal medicine, emergency medicine, or hospitalist background, where breadth of presentation matters most
    
- Prior clinical annotation, AI evaluation, medical education, or question-writing experience
    
- Grading-criteria design, resident assessment, or clinical guideline development experience
    
- Published research or sustained technical writing (please link a sample)
    

## Why this work

Most clinical AI failures are not exotic — they are ordinary questions answered with misplaced confidence. Catching that requires someone who has actually carried clinical responsibility. The standard these systems get held to is written by physicians, and here you would be writing it.

Accounting Expert (CL Funnel)

**About This Survey**

Mercor is opening a series of compliance and financial-crime engagements with leading AI labs over the coming weeks and months — spanning AML and BSA, KYC and client due diligence, sanctions screening, transaction monitoring and financial crime investigation, securities and wealth compliance, conduct and surveillance, regulatory reporting, and compliance testing and assurance. Before we finalize the scope of each, we want to build them around how compliance professionals _actually_ work, not how the field is described in textbooks or public sources.

This is a written intake designed to map out the real workflows, tools, decision points, and specialty cuts inside the profession — from the inside.

**What You'll Do**

- Complete a ~15 minute written intake about your compliance practice
    
- Describe your day-to-day workflows, how your time is split, and the workflows core to your role
    
- Explain how experienced practitioners actually divide the field from the inside — the cuts insiders use, not the textbook ones

## Non-Investment Finance Expert — AI Training & Evaluation

We're building frontier AI for complex, real-world finance work, and we need senior finance practitioners to produce and evaluate expert-grade work products that set the bar for what "correct, professional output" looks like. You'll work through realistic, document-heavy scenarios — messy source files, distractors, ambiguous guidance — and either produce the deliverable yourself or judge AI-generated attempts against a professional standard. This is hands-on finance craft, not survey-taking.

### What you'll do

- Build and review deliverables such as: PnL and mark-to-market reconciliations (trader vs. accounting, month-end marks, commissions, adjustments); vendor / AP payment reconciliations under cash constraints with controls (PO, P-card, aging); integrated 3-statement and pro-forma models including purchase-accounting impacts (ASC 805 deferred-revenue haircut, PPA amortization, synergy phasing); covenant and credit analysis; and partnership / professional-services allocations (profit-pool waterfalls, capital accounts).
    
- Reason from primary sources — term sheets, purchase/partnership agreements, trial balances, memos, emails — and separate what's material from deliberate distractors.
    
- Write clear, CFO/partner-ready narratives that explain assumptions, variances, and recommendations.
    

### Who we're looking for

- 3+ years in a hands-on non-investment finance role: product control / financial control, corporate FP&A, technical accounting, treasury / financial operations / AP–P2P, commercial-banking credit, or professional-services / partnership finance.
    
- CPA / CA / ACA / ACCA / CIMA (or equivalent) strongly preferred.
    
- Strong US GAAP / IFRS (bonus: ASC 805 & 606) and advanced Excel modeling (linked 3-statement models, reconciliations, pro formas).
    
- Comfort exercising professional judgment on incomplete or ambiguous information.
    
- Note: a CFA / investing / portfolio-management background is not required — this is operational and technical finance, not markets.

Non-Investment Finance Expert (CL Funnel)

**About the Role**

We're looking for professionals with deep, hands-on experience doing the analytical and decision-making work at the core of finance — the modeling, diligence, valuation, and judgment calls that sit behind real capital, risk, and reporting decisions. You'll design realistic, complex scenarios from your own practice area, build the supporting materials (models, memos, filings, data), then author and evaluate finance tasks used to train AI agents. This is authoring and judgment work, not throughput.

**Priority Areas — we are hiring hardest here**

\- Investment Banking & M&A: valuation (DCF, comps, precedent transactions, LBO), deal execution, fairness analysis, merger models, and diligence

\- Private Equity & Private Credit: underwriting, LBO modeling, capital structure, covenant analysis, and portfolio-company work

\- Corporate Finance & FP&A: three-statement modeling, forecasting and budgeting, variance analysis, capital allocation, and board/management reporting

**Also In Scope**

\- Equity and credit research, buy-side and sell-side coverage

\- Asset and wealth management, portfolio construction, and manager selection

\- Quantitative finance, risk management (market, credit, liquidity), and derivatives pricing

\- Treasury, capital markets, and corporate development

\- Financial modeling and technical accounting where it drives valuation or reporting judgment (US GAAP / IFRS)

\- Real estate, infrastructure, and project finance

\- Regulatory and compliance work in finance (Basel, SEC/regulatory reporting, capital adequacy)

**Requirements**

\- 3+ years of substantive, recent, hands-on finance experience at a recognized institution (investment bank, asset manager, PE/credit fund, Big Four, a large corporate finance function, or a financial regulator), and currently working in the field

\- Direct experience with the tools this work runs on — Excel/financial modeling, and where relevant Bloomberg/Capital IQ/FactSet, data rooms, ERP/consolidation systems, or quant/risk platforms

\- A 10+ hrs/week commitment

**What Makes a Strong Candidate**

We are looking for people who can construct a complicated problem, not people who process volume. The strongest signals are evidence of owning analysis and decisions: building the model that drove a live deal or investment decision, leading diligence, defending a valuation or recommendation to an investment committee or client, owning a forecast and reporting cycle, structuring a financing, or writing the memo others relied on. Within any competency we prefer the senior end (VP, Director, Principal, Managing Director, Portfolio Manager, Controller, CFO), and experience across two or more disciplines — or on both the buy side and sell side — is a strong plus. An advanced degree (MBA, MS, PhD) and/or a recognized credential (CFA, CPA, FRM, actuarial designation) is preferred, not required.

**Settings**

Not bulge-bracket only. Also boutique and middle-market advisory, PE/VC/credit funds, hedge funds and asset managers, corporate finance and treasury functions, family offices, insurers, banks and lenders, fintech, and financial regulators.

Investment Finance Expert (CL Funnel)

**About the Role**

We're looking for professionals with deep, hands-on experience in the administrative and operational work that keeps healthcare organizations running — the "back office" of a medical practice, hospital, or health plan. You'll design realistic, complex scenarios from your own practice area, build the supporting records, then author and evaluate healthcare-operations tasks used to train AI agents. This is authoring and judgment work, not throughput.

**Priority Areas** — we are hiring hardest here

- **Medical Coding:** inpatient, outpatient and pro-fee coding, risk adjustment / HCC coding, coding audit
    
- **Prior Authorization & Utilization:** initiating, submitting and tracking authorizations through payer portals; utilization review and management
    
- **Revenue Cycle Operations:** denials and appeals, A/R follow-up, payment and revenue integrity, underpayment recovery, coordination of benefits and secondary billing
    

**Also In Scope**

- Claims & billing, and full-cycle medical billing
    
- Regulatory & compliance, HIPAA privacy, healthcare internal audit
    
- Payer-side operations: claims adjudication, appeals & grievances, benefit configuration, provider network, utilization management
    
- Coding audit, Clinical Documentation Integrity (CDI), DRG validation, Health Information Management
    
- Revenue integrity, charge master (CDM), managed care and reimbursement analysis
    
- Practice, clinic and hospital administration; Director/VP of Revenue Cycle
    

**Requirements**

- 2+ years of hands-on, recent experience in a healthcare administrative / back-office role, and currently working in one
    
- Direct experience with the systems this work runs on — payer portals (Availity, Optum/Change Healthcare, Waystar, Office Ally, or individual payer hubs), EHR / practice-management platforms, encoders and computer-assisted coding tools, and/or clearinghouses
    
- A 10+ hrs/week commitment
    

**What Makes a Strong Candidate**

We are looking for people who can construct a complicated problem, not people who process volume. The strongest signals are evidence of owning exceptions and disputes: owning an appeal or payer dispute end to end, running coding or DRG audits, defending a code assignment through appeal, leading an EHR conversion or payer implementation, writing SOPs or payer-specific workflow documentation, supervising staff, or sitting on a denials or audit committee. Within any competency we prefer the senior end, and experience across two or more care settings — or on both the provider and payer side — is a strong plus.

**Settings**

Not hospitals only. Also physician groups and ambulatory practices, ambulatory surgery centers, skilled nursing and long-term care, home health and hospice, behavioral health, dialysis, infusion and specialty pharmacy, retail pharmacy and PBM prior authorization, DME suppliers, FQHCs, IDD and waiver services, health plans and TPAs, and RCM outsourcers and clearinghouses.

**Location**

The United States is our primary market. We are also open to candidates in Canada, the United Kingdom, Ireland, continental Europe, Australia and New Zealand. If you are outside the US, you are expected to work in your own country's insurance, funding or billing system — US payer knowledge is a plus, never a requirement.

**Not In Scope**

Clinical care roles (RN, LPN, NP, PA, physician, pharmacist), EMTs and paramedics, medical technicians of any kind (laboratory, radiology, surgical, pharmacy, sterile processing, respiratory, phlebotomy), reception and front-desk check-in, patient registration, appointment scheduling and appointment management at any level, call-centre script-following, medical scribes, and transcription-only roles.

Non-Physician Admin (CL Funnel)

**Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models.**

## 1\. Overview

We are hiring experienced **mechanical engineers** to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real mechanical engineering work.

Your engineering judgment is the substance of this role. You will review the quality of mechanical engineering tasks and model outputs, write the instruction specs and reference solutions that define what "correct" looks like, and help build the evaluations that show whether the model is genuinely improving. We are looking for practicing engineers who have owned real designs, analyses, or systems in industry, not generalists.

This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. The initial engagement is 2 to 3 months, with a strong possibility of extension based on performance and project needs. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams.

**Location:** Remote, within the United States.

## 2\. Key Responsibilities

- **Data QA and reviews:** Vet the quality of mechanical engineering tasks and model outputs, spotting incorrect assumptions, missing constraints, unit and tolerance errors, unsafe design choices, and answers that read well but would not pass a design review.
    
- **Instruction specs and reference solutions:** Write clear instruction specs, produce worked reference solutions to mechanical engineering problems, and define new tasks that reflect how engineering work is actually done in practice.
    
- **Benchmarks and domain depth:** Design challenging tasks and evaluation sets across areas such as mechanical design, thermal and fluid systems, structural and stress analysis, manufacturing, and controls, and help build domain-specific tools together with the research team.
    
- **Calibration:** Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit engineering judgment into explicit, teachable criteria.
    

## 3\. Core Qualifications

- **Education:** Bachelor's degree or higher in Mechanical Engineering or a closely related engineering discipline.
    
- **Experience:** 5+ years of hands-on professional mechanical engineering experience in industry, for example product design and development, thermal and fluid systems, HVAC, structural or stress analysis, manufacturing engineering, automotive, aerospace, energy, robotics, or medical devices.
    
- **Domain depth:** Genuine ownership of real engineering work, for example designing components or systems, running FEA or CFD analyses, releasing drawings and specifications, or taking products through design reviews, testing, and production.
    
- **Tools and standards:** Working fluency with common engineering tools (for example SolidWorks, CATIA, NX, Creo, AutoCAD, ANSYS, Abaqus, or MATLAB) and familiarity with relevant codes and standards (for example ASME, ASTM, ISO, and GD&T per ASME Y14.5).
    
- **Seniority:** Clear progression toward senior or lead engineering responsibility. A Professional Engineer (PE) license is a plus but not required.
    
- **AI fluency:** Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
    
- **Availability:** Able to commit reliably to 40 hours per week for an initial engagement of 2 to 3 months, with a strong possibility of extension.
    
- Excellent written communication, and the ability to give precise, well-structured written feedback.

MLOps Engineer, LLM Systems (Serving, GPU Kernels, Profiling)

The research teams behind the best-known AI models come to Mercor for careful human judgment they can't generate on their own. Your standards and attention become the rubric that frontier AI is graded against.

This is a standing listing for generalists who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match generalists in the network to projects like:

- Writing prompts and reference answers on everyday questions that have a right answer, with the context a good response has to account for
    
- Grading model output on general reasoning: whether the answer is correct, whether it follows the instruction actually given, whether it is complete without padding
    
- Flagging where a model is confidently wrong, contradicts itself earlier in the same answer, or answers a question that was not asked
    

Most contracts in this field have paid $40 to $70 an hour, set per project by scope and depth.

**What we're looking for**

- Careful reading and sound judgment, from a professional or academic background in any field
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

**Who this is for**

This pool is for people whose work does not fit neatly into one of our specialist networks, or who work across several of them. If you looked through our other listings and none of them quite described you, this is the one.

No particular credential is required. What matters is that you read carefully and can say precisely why an answer is wrong.

**How it works**

Apply here with your resume and confirm where you work from, then take a short AI interview, about 20 minutes total.

We verify your background and add you to the generalist pool.

When a project needs general reasoning work, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

**What to expect**

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched. You only need to sign up once to be eligible across all of them.

Generalist Expert

The research teams behind the best-known AI models come to Mercor for data judgment they can't generate on their own. Your standards and expertise become the rubric that frontier AI is graded against.

This is a standing listing for analysts and data practitioners who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match data practitioners in the network to projects like:

- Writing an analysis problem from work you actually shipped, with the data, the question, and the constraint, plus the reference answer a model's attempt gets graded against
    
- Grading model-written analysis and pipelines: whether the query answers the question that was asked, whether the join fans out, whether the metric means what the model says it means
    
- Flagging where a model produces a technically valid result that would mislead a decision-maker, given selection effects, leakage, or a metric that does not track the outcome
    

**What we're looking for**

- Professional experience in analytics, data engineering, statistics, or machine learning
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

**What this covers**

This pool spans data analysis, including:

- Business intelligence
    
- Data engineering
    
- Statistics
    
- Machine learning
    

Where you trained matters less than whether you have shipped analyses someone made a decision on.

**How it works**

Apply here with your resume and confirm where you work from, then take a short AI interview, about 20 minutes total.

**What the work looks like**

We match educators in the network to projects like:

- Writing a teaching problem from your own classroom or course, with the level, the common misconception, and the constraint, plus the reference answer a model's attempt gets graded against
    
- Grading model-written explanations and lesson material: whether the explanation meets the learner where they are, whether the worked example is correct, whether the assessment measures what it claims to
    
- Flagging where a model's explanation is accurate and would still confuse a student, given prior knowledge, reading level, or the misconception it fails to address
    

**What we're looking for**

- Professional experience teaching, tutoring, or designing instruction
    
- Clear written communication, since most of the work involves explaining your reasoning

The research teams behind the best-known AI models come to Mercor for electrical engineering judgment they can't generate on their own. Your standards and expertise become the rubric that frontier AI is graded against.

This is a standing listing for electrical engineers who want AI training and evaluation work, not a specific job opening. It stays open whether or not a matching project is running this week.

New projects start on short notice, so instead of posting and pulling a listing each time, we keep one open per field and draw from it when one begins.

**What the work looks like**

We match electrical engineers in the network to projects like:

- Writing a circuit or systems problem from work you have done, with the specification, the constraints, and the operating conditions, plus the reference answer a model's attempt gets graded against
    
- Grading model-written design and analysis: whether the topology suits the requirement, whether the noise and stability margins hold, whether the timing closes
    
- Flagging where a model's design simulates cleanly and fails on a real board, given parasitics, tolerance stack-up, or interference
    

Past rates have run $70 to $120 an hour, set per project by scope and depth.

**What we're looking for**

- A degree in electrical engineering, with professional design, test, or systems experience
    
- Clear written communication, since most of the work involves explaining your reasoning
    
- Comfort with ambiguous tasks, and willingness to flag unclear instructions
    

Where you trained matters less than whether you have debugged your own design on the bench and found out what the simulation missed.

**How it works**

Apply here with your resume and confirm where you work from, then take a short AI interview, about 20 minutes total.

We verify your background and add you to the electrical engineering pool.

When a project needs electrical engineering expertise, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

**What to expect**

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

When a project needs investment banking expertise, we invite matching people from the pool to that specific listing. It names the rate, the hours, and the client, and any hiring decision is made there.

**What to expect**

This listing does not accept or reject candidates, so you will not get a decision on it. We reach out when a project matches your background. Depending on what our clients are running, that can be within a week or several months.

Finishing the domain expert interview and joining every network you qualify for both improve your odds of being matched. You only need to sign up once to be eligible across all of them.

Investment Banking Expert

We are building a large set of evaluation tasks for the construction and property field. Each task starts from real drawings, documents and site photos, and asks for the same structured deliverable you would produce at work: an egress analysis, a correction list, a plan review decision. You author the task and the correct answer, and a second reviewer in your discipline checks it before it ships.

What you would be building
Tasks drawn from real fire and life safety review work, including: egress and life safety plan check, fire access plan review, fire alarm review from both the design engineer and the fire marshal seat, sprinkler review from the engineer, fire marshal and property insurer seats, hazardous materials control area review, fire occupancy video inspection, firestop penetration photo verification, and fire system inspection, testing and maintenance report review.

Who we are looking for
You currently hold, or recently held, the seat that reviews fire and life safety design: fire marshal or fire prevention plan reviewer, fire protection engineer, or sprinkler and fire alarm designer-reviewer.
Fire marshal appointment, NICET Level III or higher, or PE in fire protection.
3 or more years in the seat, US based, working to IBC, IFC and NFPA standards. We prefer 8 or more years.
You can mark up plan sets and read hydraulic calculations and device layouts.

What makes someone excellent here
The hard part is not citing the standard, it is knowing which occupant load, travel distance or coverage gap gets waved through. Standouts have usually trained junior inspectors or reviewers, written department correction language or an SOP, done acceptance testing as well as plan review, or worked across several NFPA editions and can say what changed and when it applies.

Probably not a fit
Firefighters and fire officers without plan review or inspection responsibility, sprinkler installers without design or review work, alarm technicians who service rather than design systems, and general safety or OSHA specialists.

Paid hourly at $45 to $60 depending on experience, with a path to grow your rate as the project scales.

Fire & Life Safety Reviewer — Vulcan

We are building a large set of evaluation tasks for the construction and property field. Each task starts from real drawings, maps, aerials and site documents, and asks for the same structured deliverable you would produce at work: a plan review comment set, a survey exception schedule, a measured read. You author the task and the correct answer, and a second reviewer in your discipline checks it before it ships.

What you would be building
Tasks drawn from real site, civil and survey work, including: civil grading plan review, erosion and sediment control plan review, stormwater design plan review, roadway plan check, work-zone and traffic control plan review, utility service drawing review, floodplain permit review, civil RFI response review, landscape ordinance and tree protection review, earthwork quantity verification and stockpile volume certification, ALTA Table A survey items, title survey exception review, closing survey setback review, elevation certificate photo checks, topographic map review and map stack reading, historic aerial and Sanborn map dating, and assessor sketch verification.

Who we are looking for
You currently hold, or recently held, the seat that produces or reviews site, civil and survey work: civil engineer, land development engineer, land surveyor, or geospatial or Phase I environmental analyst.
PE in civil engineering, or PLS for the survey and mapping work.
3 or more years in the seat, US based, working to US standards and state DOT or local land development practice. We prefer 8 or more years.
You are comfortable moving between drawing sets, aerials, topographic maps and parcel data.

What makes someone excellent here
The hard part is not reading the sheet, it is knowing which quantity, contour or exception a reviewer takes on faith. Standouts have usually reviewed submittals for an agency or DOT, mentored EITs or survey crews, carried a project through agency resubmittal cycles, or worked across several jurisdictions and can name what each one checks differently.

Probably not a fit
GIS analysts who have not reviewed engineered drawings, drone pilots without survey credentials, environmental scientists whose work is sampling rather than site plan review, and CAD technicians without design or review responsibility.

Paid hourly at $45 to $60 depending on experience, with a path to grow your rate as the project scales.

Civil / Survey Engineer — Vulcan

We are building a large set of evaluation tasks for the construction and property field. Each task starts from real drawings, documents and site photos, and asks for the same structured deliverable you would produce at work: an RFI response, a coordination comment set, a marked-up set. You author the task and the correct answer, and a second reviewer in your discipline checks it before it ships.

What you would be building
Tasks drawn from real design and coordination work, including: architectural RFI response review, architectural set QC check, technical peer review, cross-sheet coordination review, constructability review, redline back-check, design change approval, addendum change scoping, as-built drawing production, pre-bid drawing scope review, drawing-set document control, commissioning design review, and shop drawing review for interiors, millwork and building envelope details.

Who we are looking for
You currently hold, or recently held, the seat that produces and coordinates permit and construction drawing sets: architect of record, project architect, job captain, or design coordination lead.
Licensed architect. In lieu of a license, 8 or more years as a project architect or job captain producing permit sets.
3 or more years in the seat, US based, working in US model code jurisdictions. We prefer 8 or more years.
You can mark up drawing sets and details. Bluebeam Revu or equivalent.

What makes someone excellent here
The hard part is not answering the RFI, it is knowing which cross-sheet conflict a rushed reviewer signs off on. Standouts have usually run set QC or back-check on other people's drawings, mentored job captains, maintained office standards or a detail library, or worked both sides of the RFI process as designer and as reviewer.

Probably not a fit
CAD or BIM drafters without authorship of the set, renderers and visualization specialists, interior decorators, and PMs who coordinate schedules rather than drawings.

Paid hourly at $45 to $60 depending on experience, with a path to grow your rate as the project scales.

Architect — Design Coordination (Vulcan)

We are building a large set of evaluation tasks for the construction and property field. Each task starts from real drawings, documents and site photos, and asks for the same structured deliverable you would produce at work: a correction letter, a review decision, a marked-up set. You author the task and the correct answer, and a second reviewer in your discipline checks it before it ships.

What you would be building
Tasks drawn from real permit review work, including: building plans examiner review, code consultant plan review, third party and private provider plan review, accessibility and ICC A117.1 review, energy code drawing checks, occupancy classification and storefront change of use, zoning site plan review, permit intake completeness screening, as-built versus permit deviation, and specialty occupancy review for healthcare facilities, schools, food service and public pools.

Who we are looking for
You currently hold, or recently held, the seat that reviews permit drawing sets for code compliance: a building department plans examiner, a third party or private provider plan reviewer, or a code consultant.
ICC Building Plans Examiner certification (B1, B2 or B3), or current or recent employment doing AHJ or third party plan review. There is no degree requirement for this role.
3 or more years in the seat, US based, working in US model code jurisdictions (IBC, IEBC, IECC, ICC A117.1). We prefer 8 or more years.
You can mark up and measure a plan set. Bluebeam Revu or equivalent.

What makes someone excellent here
The hard part is not applying the code, it is knowing exactly what a careless reviewer would miss. Standouts have usually trained junior examiners, written or maintained a comment library or correction template, done QA on other reviewers' work, or worked across several code editions and jurisdictions and can say precisely what changes between them.

Probably not a fit
General contractors and superintendents without plan review responsibility, estimators, CAD drafters, and permit expediters who file applications but do not review them.

Paid hourly at $45 to $60 depending on experience, with a path to grow your rate as the project scales.

Code Plan Reviewer (Plans Examiner) — Vulcan

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real financial analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers company event propagation: identifying the companies related to an upcoming event and estimating how the catalyst should transmit to each of them.

## What you will do

- Map suppliers, customers, competitors, distributors, substitutes and geographic exposure from EDGAR filings, footnotes, exhibits, transcripts and industry data
    
- Identify related companies ahead of an event and separate direct exposure from weak thematic correlation
    
- Estimate direction, magnitude, horizon and confidence, and name the revenue, margin, earnings or valuation mechanism behind each
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- A senior sector PM, lead equity analyst, or event-driven investor with deep knowledge of a specific industry
    
- Hands-on experience mapping a company's economic network from primary filings, not from screens or third-party tags
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: top multi-manager and event-driven funds, leading sector teams at major asset managers and banks, and elite specialist research firms — for example Citadel, Millennium, Point72, Balyasny, D. E. Shaw, and top sell-side sector franchises. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

Company Analysis Expert — Event Propagation

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real macro analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers non-G7 central bank communication. We staff separately by country: a broad global-macro profile is not enough, and we are looking for depth on one specific central bank.

## What you will do

- Interpret statements, minutes, speeches and wording changes from a specific non-G7 central bank in their source language
    
- Compare current language against prior guidance and prevailing market expectations
    
- Assign a calibrated dovish-to-hawkish score and spell out the implications for rates, FX and equities
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- A former economist or adviser from the relevant central bank, or a senior local rates or FX strategist who covered it through multiple policy cycles
    
- Professional fluency in the source language
    
- Deep knowledge of that bank's reaction function and communication style, and experience reading it in real time
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: the exact central bank, the BIS, the IMF, leading local institutions, top emerging-markets teams at global banks, and established macro funds. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

Central Bank Expert — Non-G7 Policy Communication

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real financial analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers single-name equity analyst publications: predicting when a named sell-side analyst will publish after a catalyst, and what that update will contain.

## What you will do

- Forecast the timing and content of a named analyst's post-catalyst research note
    
- Reason from filings, earnings, transcripts, estimates, valuation and ratings to an expected published view
    
- Document the internal research workflow that determines how and when an equity research report gets produced
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- A former lead sell-side equity analyst or highly senior research associate who personally published post-catalyst research in the exact sector
    
- Deep command of filings, earnings, transcripts, estimates, valuation, ratings, and the internal workflow behind an equity research report
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: Institutional Investor-ranked teams and leading research franchises such as Goldman Sachs, Morgan Stanley, JPMorgan, Bank of America, Citi, UBS, Barclays, Bernstein, Jefferies and Wolfe Research. Former colleagues, direct coverage rivals, and senior buy-side consumers of a named analyst's work are especially valuable. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

Equity Research Expert — Single-Name Analyst Publications

## About the work

We are building expert-authored forecasting and research data used to evaluate and improve AI models on real political and financial analysis. Each task asks a practitioner to reason from a fixed evidence cutoff — no hindsight — and document the judgment a strong analyst would have made at that moment.

This role covers political report authorship: elections, polling, and political-risk events.

## What you will do

- Author point-in-time political reports and forecasts from a stated evidence cutoff
    
- Make and document directional judgments about polling, win probabilities, and market-implied odds
    
- Explain the causal mechanism behind an event's expected political and market impact
    
- Review model-generated analyses and grade them against your own standard
    

## Who we are looking for

- A senior elections forecaster, campaign strategist, polling or statistical-methodology expert, or political-risk analyst
    
- A record of making live judgments about polling, win probabilities, or odds — not retrospective commentary
    
- Strong polling literacy and causal event analysis
    
- Typically 8+ years of direct experience, or unusually strong evidence of equivalent performance
    

Backgrounds we look at first: top national polling and election-forecasting organizations, major decision desks, senior analytics teams from presidential, Senate or governor races, and political-risk desks at leading banks, funds, or firms such as Eurasia Group and EIU. Brand-name experience is a strong first-pass signal but is not a hard requirement — direct experience and performance on the work sample determine who qualifies.

## Not a fit

Pure communications, journalism, or academic profiles without demonstrated forecasting, polling, or probabilistic judgment.

## Point-in-time discipline

Every task is graded on reasoning from the stated cutoff without hindsight, data leakage, confidential information, or material non-public information.

Political Expert — Elections Forecasting & Political Risk

## About the work

Mercor is assembling a panel of chemistry and chemical safety experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.

You will:

- Write challenging single-turn prompts in your domain, labelled across three levels: benign, dual-use, and adversarial.
- Evaluate the responses that come back against a defined policy standard, and judge whether each was handled correctly.
- Write the reference answer — what a correct response looks like, and the technical reasoning for why.

This domain lives on the dual-use line more than most. The same casework knowledge that identifies a substance describes how it was produced; the same precursor list that supports an investigation is a shopping list read backwards. A model that refuses a routine identification or casework question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have done casework — identifying substances and precursors, and defending the conclusion in a report or on the stand. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same precursor knowledge that identifies a clandestine route is the route. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Controlled substance casework in a forensic laboratory — identification and quantitation
- Clandestine laboratory response, precursor identification and scene chemistry
- Forensic toxicology — postmortem or human performance casework
- Seized-drug and precursor trend monitoring or intelligence analysis
- Expert testimony and report writing on chemical casework

## What this role demands beyond technical depth

This is writing-intensive work. Every judgment you make needs a written rationale that a non-specialist can follow. Prior technical writing, published research, or expert witness experience is a strong signal; please include a sample or link. You will also be reading and writing about misuse scenarios in your field for sustained periods. We brief experts on this in advance, and you can pause or step away at any point without penalty.

## Before you apply

Your work here will not involve, and must not draw on, classified or export-controlled information, or anything covered by an NDA or prepublication review obligation. If you hold such obligations you may still be a good fit; tell us in your application and we will scope the work accordingly.

Forensic / Toxicological Chemist

This domain lives on the dual-use line more than most. The same dispersion model that sites a plant and sets an evacuation radius also predicts an exposure; the same hazard analysis that finds a failure path is a list of failure paths. A model that refuses a routine exposure-limit question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have assessed real exposures and real process hazards, and signed off on the controls. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same release model that protects a community estimates a consequence. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Certified industrial hygienist — exposure assessment, sampling strategy, control banding
- Process hazard analysis — HAZOP, LOPA, what-if studies, management of change
- Toxic release and dispersion modelling — consequence analysis, AEGL/ERPG criteria, facility siting
- Ventilation, containment and PPE programme design for chemical hazards
- Regulatory compliance — PSM, Seveso, COMAH, OSHA or national equivalents

This domain lives on the dual-use line more than most. The same method that detects a hazardous compound at trace level defines the threshold someone would try to stay beneath; the same library entry that identifies an unknown tells you what a screen will and won't see. A model that refuses a routine method-validation question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for analysts who have built and validated methods for hazardous compounds — people who know what a detection limit really means and what it implies. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same detection method that finds a compound describes how to evade the screen. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Detection and identification of hazardous compounds — GC-MS, LC-MS/MS, IR, NMR
- Method development and validation for trace-level analysis
- Environmental, occupational or emergency-response sampling and analysis
- Reference standards, spectral libraries and unknown identification
- Laboratory accreditation, QA/QC and proficiency testing

This domain lives on the dual-use line more than most. The same route design that scales a medicine underpins a controlled compound; the same impurity profile that proves a clean process identifies how something was made. A model that refuses a routine scale-up or kinetics question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for chemists who have actually run routes and scaled them — bench to pilot to plant — and who know which requests are ordinary process chemistry and which are asking for something else. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same route knowledge that shortens a synthesis serves whoever is shortening it. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Synthetic route design and development in pharmaceutical, agrochemical or fine chemicals
- Process chemistry and reaction engineering — optimisation, kinetics, impurity control
- Scale-up from bench to pilot to plant, with the safety review that goes with it
- Precursor sourcing, controlled-substance registration or regulatory chemistry
- Method development and troubleshooting in a GMP or equivalent quality environment

This domain lives on the dual-use line more than most. The same toxicology that sets a countermeasure dose describes an exposure someone might intend; the same decontamination data that protects responders tells you what defeats it. A model that refuses a routine countermeasure or PPE question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have worked chemical threats from the defensive side in an institutional setting — countermeasures, protection, detection, verification. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same agent properties that drive a treatment protocol drive a threat assessment. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Chemical defence research at USAMRICD, DoD, CDC or an allied national institute
- Toxicology of chemical warfare agents and medical countermeasure development
- Decontamination, protection and detection research for chemical threats
- CWC-related work — verification, destruction, designated laboratory analysis
- Consequence assessment and medical management of chemical exposure

Chemical Defense Researcher

## About the work

Mercor is assembling a panel of energetic materials and propulsion experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.

- Write the reference answer — what a correct response looks like, and the technical reasoning for why.

This domain lives on the dual-use line more than most. The same design that breaks rock for a highway cut is a description of directed energy release; the same magazine and transport rules that keep a crew safe are a map of where material sits and how it moves. A model that refuses a routine vibration-compliance question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for licensed practitioners who handle, store and move specialty materials as a daily responsibility, and who sign for them. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same inventory and transport detail that satisfies an auditor is what a diversion would exploit. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Licensed blaster or blasting engineer — mining, quarrying, construction or demolition
- Blast design and vibration control — timing, burden, seismograph monitoring, regulatory limits
- Magazine management, inventory reconciliation and transport of specialty materials
- Storage compatibility, security and regulatory compliance for a commercial licensee
- Training, certification or auditing of blasting crews

This domain lives on the dual-use line more than most. The same propulsion analysis that qualifies a motor for flight describes a capability; the same safe-and-arm logic that keeps a system inert is the part someone would want to defeat. A model that refuses a routine performance or qualification question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

This is the engineering half of the domain: we're looking for people who have designed, qualified or tested propulsion and initiation systems, with real hardware and real test data behind them. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same effects model that sizes a safety standoff also sizes an intent. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Munitions or warhead design and effects engineering
- Solid, liquid or hybrid propulsion system design, test and qualification
- Terminal effects modelling — blast, fragmentation, penetration
- Fuzing, safe-and-arm and initiation system engineering
- Test range engineering and instrumentation for propulsion or ordnance

Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have worked scenes and casework under a national certification — identifying materials after the fact, and inspecting the licensees who hold them. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same residue signature that closes a case describes a recipe in reverse. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Federally certified explosives specialist or national equivalent — scene and materials analysis
- Forensic laboratory identification of energetic materials and post-blast residues
- Post-incident analysis and reporting for an agency or laboratory
- Regulatory inspection of licensees and permittees — storage, records and diversion indicators
- Expert testimony or casework on energetic materials

## What this role demands beyond technical depth

This is writing-intensive work. Every judgment you make needs a written rationale that a non-specialist can follow. Prior technical writing, published research, or expert witness experience is a strong signal; please include a sample or link. You will also be reading and writing about misuse scenarios in your field for sustained periods. We brief experts on this in advance, and you can pause or step away at any point without penalty.

## Before you apply

Your work here will not involve, and must not draw on, classified or export-controlled information, or anything covered by an NDA or prepublication review obligation. If you hold such obligations you may still be a good fit; tell us in your application and we will scope the work accordingly.

Federal Certified Materials Specialist / Incident Analyst

## About the work

Mercor is assembling a panel of energetic materials and propulsion experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.

You will:

- Write challenging single-turn prompts in your domain, labelled across three levels: benign, dual-use, and adversarial.
- Evaluate the responses that come back against a defined policy standard, and judge whether each was handled correctly.
- Write the reference answer — what a correct response looks like, and the technical reasoning for why.

This domain lives on the dual-use line more than most. The same formulation work that qualifies a propellant or a display composition sits next to something nobody should be helped with; the same sensitivity data that protects a production line reads as a specification from the other side. A model that refuses a routine thermal-stability question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

This is the chemistry half of the domain: we're looking for people who have formulated, synthesised and tested specialty energetic materials in a licensed or government facility, not modelled them from a distance. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same sensitivity result that sets a safe handling limit is what someone else would want to design around. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Formulation chemist for pyrotechnics, propellants or specialty energetic materials
- Synthesis and characterisation of energetic compounds in a licensed or government facility
- Performance and sensitivity testing — calorimetry, thermal stability, small-scale safety testing
- Scale-up and process safety for energetic material production
- Solid or liquid rocket propellant development — binders, oxidisers, burn-rate modifiers

This domain lives on the dual-use line more than most. The same assessment that tells a technician how to approach a device tells someone else how it was meant to work; the same compatibility data that keeps a magazine safe describes what stays stable elsewhere. A model that refuses a routine storage or render-safe question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for public safety professionals who have assessed real devices — the render-safe and post-incident side, held under certification and command accountability. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same assessment that makes a device safe explains how it was built. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Certified bomb technician or hazardous device operator — device assessment and render-safe procedures
- Military EOD with civilian public-safety, training or instruction experience
- Bomb squad commander or training officer — team qualification, equipment and protocols
- Post-blast investigation and device reconstruction
- CBRNE technical response — standoff assessment, robotics and disruption tools

This domain lives on the dual-use line more than most. The same control list that stops a shipment tells a procurement agent what to avoid declaring; the same pathway analysis that informs policy is a roadmap read from the other direction. A model that refuses a routine export-classification question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have worked proliferation questions professionally — export control, treaty implementation, or programme analysis — and who can tell a compliance question from a circumvention question. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same control list that blocks a transfer also names what to route around. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Export control licensing, classification or enforcement — dual-use lists, catch-all controls, end-user screening
- Treaty and agreement implementation — NPT, CTBT, safeguards agreements, bilateral cooperation agreements
- Proliferation pathway and programme analysis at a laboratory, agency, ministry or research institute
- Sanctions, procurement network or illicit trade analysis
- Open-source and technical analysis of nuclear programmes

This domain lives on the dual-use line more than most. The same signature that attributes a sample is the one someone would want to suppress; the same detection limit that catches material moving can be read as a threshold to stay under. A model that refuses a routine measurement-methodology question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have characterised real nuclear material — detection, attribution, and the analytical work behind a defensible conclusion. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same signature that identifies a source tells you what to hide. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Nuclear forensics casework or international exercise participation — sample characterisation and attribution
- Radiochemical and mass-spectrometric analysis — isotopics, age dating, impurity and process signatures
- Detection and interdiction technology — portal monitors, handheld identification, search operations
- Material signature libraries, reference materials and attribution methodology
- Pre- or post-detonation forensics research at a national laboratory or agency

Forensic Scientist — Nuclear Materials

## About the work

Mercor is assembling a panel of nuclear materials and safeguards experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.

- Evaluate the responses that come back against a defined policy standard, and judge whether each was handled correctly.
- Write the reference answer — what a correct response looks like, and the technical reasoning for why.

This domain lives on the dual-use line more than most. The same material-balance calculation that closes an inspector's account can be used to hide what is missing from it; the same protection assessment that hardens a facility maps its weaknesses. A model that refuses a routine material-accounting question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have been responsible for keeping nuclear material where it belongs — material control and accountability, physical protection, and the assessments that test both. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same vulnerability assessment that closes a gap also describes it. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Material control and accountability (MC&A) programme design, operation or assessment at a national laboratory or licensee
- Physical protection system engineering — sensors, barriers, delay, response force, performance testing
- Vulnerability assessment and adversary path analysis for nuclear facilities

This domain lives on the dual-use line more than most. The same material-balance calculation that closes an inspector's account can be used to hide what is missing from it; the same fuel-cycle step that supplies a power reactor is the one a proliferation pathway runs through. A model that refuses a routine criticality-safety question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who have worked the fuel cycle itself — enrichment, reprocessing, fabrication, criticality safety — and who know which parameters are routine engineering and which ones only matter to someone going somewhere else with them. What matters most is being able to tell a routine professional question from one that's fishing for something else. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Enrichment, conversion or fuel fabrication engineering — process design, operations, throughput
- Reprocessing and back-end fuel cycle — separations, waste streams, spent fuel management
- Criticality safety engineer — criticality safety evaluations, limits and controls, accident analysis

## Background we're looking for

We're looking for people who have verified nuclear material rather than read about it — inspection regimes, accountancy, and the judgment calls that come with an unresolved discrepancy. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same material-balance figure that closes an account can be used to conceal a diversion. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- IAEA, Euratom or state-system (SSAC/RSAC) inspector — inspection planning, verification, reporting

This domain lives on the dual-use line more than most. The same isotope underpins cancer therapy and industrial radiography; the same shielding calculation protects a worker and conceals a source. A model that refuses a routine dose question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

## Background we're looking for

We're looking for people who produce and handle medical isotopes — the legitimate-use half of the dual-use line, held as a real custody responsibility. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same activity and shielding figures that let a patient go home describe a source someone else wants to move quietly. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

Examples of relevant backgrounds (ideally with red-teaming experience):

- Nuclear medicine or radiopharmacy physicist — therapy dosimetry, I-131, Lu-177 and Y-90 work, patient release criteria

We're looking for people who have planned for or responded to a radiological event — the consequence, contamination and protective-action side, held as a real responsibility rather than a tabletop interest. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same dispersal model that drives an evacuation decision also describes an effect someone might want. You will be writing prompts that sit exactly on that line, then judging whether the model held it.
